Bash doesn't generally produce much output by itself.  Rather, it's used
to execute commands, and some of those commands may produce output.

If you want to filter the output of a script as described above, the best
way would be to pipe the script through sed:

  ./myscript | sed 's,Hello,Hi,g'

If that doesn't satisfy your requirement, then you need to explain a bit
more about what you require.  (Modifying bash at the source code level to
filter the output of a script is a completely unsuitable approach.)
